FRANK IF. MILLER, OF YANK'ION, SOUTH DAKOTA, ASsIG'NOR TO ELIVIER HICKS, OF

RUBBING-POST.

To all whom it may concern: r

I Be it known that I, FRANK F. MILLER, a citizen of the United States, residing at Yankton, in the county of Yankton and State of South Dakota, have invented certain new and useful Improvements in Rub hing-Posts, of which the following is a specification. v

This invention relates to rubbing posts for use in animal husbandry, and is designed more particularly for supplying oil or disinfectants to hogs and small stock.

One object of the invention is to effect an economy in the use of theoil or other'liquid and to permit a limited discharge of the same when an animal rubs against the actuating lever or rubbing bar. j

A further object of the invention is to pre-' vent discharge of the liquid except when the rubbing bar is actuated, and a further object of the invention is to protect the supply of liquid from contamination.

' A further object of the invention is to pro vide means whereby the quantity discharged at any one time may be regulated, and a still further object is to provide means whereby the rubbing bar will be permitted to swing freely at all times but will be limited in its movement and will not be liable to choke with mud.

Other incidental objects of the invention will appear as the description proceeds, and the invention resides in certain novel features which will be particularly pointed out in the claims following the description.

In the drawings Figure 1 is a front elevation of a rubbing post embodying my improvements;

Fig. 2 is a side elevationof the same;

I Fig. 3 is a vertical section taken longitudinally ofthe trough;

Fig. 4 is a detail perspective view of the trough, the upper end of the rubbing bar and the keeper or bracket by which the rubbing bar is maintained in its position relative to the trough, these partsbeing shown detached but approximately in their proper relative positions;

desired dimensions and may be secured to the-side of a building, a fence post, a tree or other object located where it will'be accessible to the animals. At an intermediate point of the height of this post or base board, I secure a trough 2 which is preferably a casting having lateral lugs 3 at one I end which are provided with openings or notches 4 whereby fasteningbolts 5 may be inserted through the lugs and the base board or post 1 to secure the trough rigidly in place. The outer end of the casting presents a circular wall 6 whereby a well is formed to containa supply of liquid. At the center of this wellis a small lug or projection 7 the purpose of which will presently appear.

' The circular-wall 6 is connected with the lugs 8 by parallel side walls 8, and between the said sidewalls extends a rear wall or web 9. The bottom of the trough is vraised adjacent the rear wall 9, as shown most clearly at 10 in Fig. 3, and through the said raised portion 10 is provided a passage or opening 11 through which the liquid may flow to the rubbing bar. From the bottom of the trough, in advance of the raised portion 10, rises a pin 12 which is adapted tospout and seal the same so as to prevent the escape of the liquid and, when the container is fitted over the pin 12, the valve will be moved from the spout by the upper end of the pin sufficiently to permit the liquid to flow into the trough, as will be readily understood on reference to Fig. 3. It will also be understood that, while inverting the con tainer, the end of the spout will be covered by the thumb or in any convenient manner to prevent loss of liquid.

- Secured to the base board or post 1,.=immediately above the trough and in position to rest upon the upper edges of the walls thereof, is a keeper or cover 16 havingan upstanding lug 17,. at its rear endthrough an .o pening18 in which is inserted v al bolt 19 to secure thesaid lug firmly to. the base board. This keeper is provided adjacent its front end with an opening which receives the spout of the serves to guide the spout to its proper position and also aids in maintaining the container in place. Between its ends, this" keeper or cover is provided with a transverse rib 21 having a groove 22 in'its under side which receives a pin or bolt 23 which is inserted throi'igh the arms 24 at the upper end of the rubbing bar to pivotal'ly support the said bar upon the trough, as shown in. Fig. The pivot 23, it will be noted, located. practically in the same vertical plane as the opening. 11 so that the upper end 25' of the rubbing bar will be directly under the said opening. This upper end of the rubbing bar is convex so that the oil dropping thereon. will be directed onto the front surface of the rubbing bar and upon the said front surface is provided a series of downwardly inclined ribs or bafhes 26 which extend alternately from the opposite sides or edges of the bar, where' by the oil will be caused to flow tortu'ously the surface of the bar and will, con sequently, be retarded in its passage to the loi'ver end of the bar. The arms 2 1, which rise from the rubbing bar and pivotally supp rt the same, are provided with eyes or perforated lugs 27 at their upper ends which are adapted to receive a presser rod or arm 28 which is preferably in the form of a rod projecting forwardly from the upper end i of the rubbing bar past the container and having its front end turned inwardly, as shown at 29, and then downwardly, as shown at 30, to bear upon the upper side of a plunger or cup piston 31. This plunger or piston 31 plays in tie well 6 and is supported freely therein by a coiled spring 32 which is disposed between the upper end of the plunger and the bottom of the well and. has its lower end fitting around the stud I or lug 7 so as to be re '1 ined in its operative position.

It will be readily understood from the foregoing description, taken in connection with the accompanying drawings, that, when an animal rubs against the rubbing bar, in-

dicated as a whole by the reference numeral the said bar will be caused to swmg about its pivot so as to approach parallel V ism with the base board 1, the result being that the presser arm 28 will be moved downwardly and will depress the plunger 31 against the tension of the spring 32 and thereby eject a small quantity of the oil from the well. The ejected oil will rise over the raised portion 10 of the trough and escape through the opening 11 onto the convex surface 25 of" the rubbing bar, whence it will be passed over the front face of the said bar, as previously described; The spout l4: isto be ofsuc'h length that in )r and thereby ,7

flow will be arrested.

depressed, its lower end will enter th the lower end thereof will lie just below the upper surface of the raised portion 10 of the trough. Qensequently, the oil from the container 13 will flow into the trough until it rises to the level of the lower end of the spout and will seal the same so that further When the plunger is liquid and the pressure exerted by the plunger will cause the liquid to rise over the raised portion 10 and escape. As long as the animal presses against the rubbing bar, the plunger will be held depressed and, quentl'y, but one discharge of the liquid will be made; As theplunger or piston has an open bottom but closed top and sides, an air cushion will be formed under the same to prevent it being moved violently so as to: splash the liquid and, consequently only a smallquantity of the liquid will be discharged. lVhen the parts return to their normal positions, upon the animal leaving the rubbing bar, the piston will serve to some extent as a pumpto such an additional supply of liquid from the container. It will be readily understood that the presser arm 28 may be disposed at either side of the rubbing bar and may be set to vary the stroke of the plunger by adjusting the nuts 3% which secure thearmin the upper end of the rubbing. bar.

The lower end of the rubbing bar is provided with a depending lug 35 to which is pivoted the upper end of a detent or curved block 36 having lateral pins or stops 3? at its lower end. wardly through a slot 38 in the top plate of a bracket 39 which is secured to the lower end of the base board 1 and plays freely in the said slot. When the rubbing bar is in the position shown in Fig. 2,'the pins 3-7 will contact with the under side of the top branch of the bracket 39 and will thereby limit the outward movement of the bar. \Vhen an animal rubs against the bar, the block 36 will move downwardly through the slot 38 and will thereby prevent lateral movement of the rubbing bar, as will bereadily understood As this bar will be in'moveinent almost constantly, it will be readily understood that mud cannot collect in the slot 38 so as to clog the action of the device.

The container is supported upon the cover 16 by a bail l0 which is secured to the end of the container and is so disposed as to it around the spout l4: and provide a feet This block 36 is inserted np- 41 adapted to -rest upon the coverlti, as

board. The base board is preferably of wood so as to reduce the weight for shipping purposes. Moreover, when the parts are clamped against a wooden base board, the lugs will be partly embedded in the board so as to hold firmly, whereas, if they were clamped against a smooth metal post, they would work loose through use and the working parts would get out of alinement. The notches in the several lugs provide for accurate alinement in setting up the device.

It is thought to be clear from the foregoing description that I have provided an exceedingly simple device which may be a readily set up at any desired place and by the use of which the disinfectant, insecticide or other liquid may be economically supplied to the animals.
